questions about controls

[xudeutsch]

as far as i know, in asp.net there are such classification:

server control(including HTML Server Control and Web Form Control), user
control(.ascx) and custom control(.dll).

I have a .net windows forms control hosted in Internet Explorer,

the use of it like following:
<object id="MyControl"
classid="http:..\control\MyControl.dll#MyControl.MyGraphicControl"
height="966" width="1280">
<param name="myFile" value="test.GED" />

</object>"
which kind of control does "MyControl" belongs to?

thank you
